Re: Re: [ns] how to dump routing talbe?

[zhangkehuan@163.net]

thanks to help me solve this problem. but i have encountered another problem. in 
your attachment,you use "$ns dump-routelogic-nh" in procedure "mydump{}". however
, this mothed will not dump to a file,but to the screen. i have checked the tcl-s
ource file "ns-route.tcl" under "ns/tcl/lib" directory, and found that i its code
,"Simulator instproc dump-routelogic-nh {}",it is writen as follows:

                set nh [$routingTable_ lookup $i $j]
                if { $nh >= 0 } {
                    puts -nonewline "$nh\t"
                }

i think i could dump these infomation to a file with this tcl-script:
               puts -nonewline $filehandle "$nh\t"
where "$filehandle" is the return by "open" 
my quesiton is :  can i write such a procedure of myself ,make it work ,and get 
the routing table in a file , also without re-compiling the whole ns under linux(
i won't to re-compile ns).
my working environment is : "linux5.2 kernel2.0.36, ns-allinone-2.1b7a"
thanks in advance.
yours zhangkehuan
